For questions asking for Boolean Expressions: All the answers will be in Uppercase letters ABCD... Use the exclamation point style NOT   !   operator: A!B, !C!D, A!CD, !(A + !C), ... Each term will have individual letters in alphabetical order:  AB, !CD, ACD, B!D, ... Variables that are ANDed together will have no space between the variables:  ACD,  B!CD, !AC!D, etc Terms that are ORed together in POS style format will be in parenthesis with spaces between the letters and the OR  +  symbols:  (A + B + D)(C + D), (A + B + C), !(B + C), !(A + C + !D), ... For answers with multiple terms I tried to arrange them so that the terms with the fewest NOT operators  !  are first and the most are last:  AB + !BCD + !A!B + !A!B!D   1)To implement a 1-bit adder, write a Boolean expression for the Carry function.
